### Claude Desktop Configuration

Users add this to `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "sap-datasphere": {
      "command": "npx",
      "args": ["@mariodef/sap-datasphere-mcp"],
      "env": {
        "DATASPHERE_BASE_URL": "https://your-tenant.eu20.hcs.cloud.sap",
        "DATASPHERE_CLIENT_ID": "your-client-id",
        "DATASPHERE_CLIENT_SECRET": "your-client-secret",
        "DATASPHERE_TOKEN_URL": "https://your-tenant.authentication.eu20.hana.ondemand.com/oauth/token"
      }
    }
  }
}
```

## How It Works

### Installation Flow

1. **User runs**: `npm install -g @mariodef/sap-datasphere-mcp`
2. **npm downloads**: Package from npm registry
3. **Postinstall runs**: Attempts `pip install sap-datasphere-mcp`
4. **Done**: User can now run `npx @mariodef/sap-datasphere-mcp`

### Runtime Flow

1. **User runs**: `npx @mariodef/sap-datasphere-mcp`
2. **Wrapper checks**: Python 3.10+ availability
3. **Wrapper verifies**: Python package installed
4. **Wrapper launches**: `python -m sap_datasphere_mcp_server`
5. **Server starts**: MCP server ready for connections

## Benefits for Users

### Before (PyPI only):
```bash
# Users needed to know Python
pip install sap-datasphere-mcp
python -m sap_datasphere_mcp_server

# Claude Desktop config
"command": "python",
"args": ["-m", "sap_datasphere_mcp_server"]
```

### After (npm package):
```bash
# Simple npm install
npm install -g @mariodef/sap-datasphere-mcp

# Or use directly with npx
npx @mariodef/sap-datasphere-mcp

# Claude Desktop config
"command": "npx",
"args": ["@mariodef/sap-datasphere-mcp"]
```

**Key Advantages:**
- No Python knowledge required
- Automatic dependency management
- Works with `npx` (no global install needed)
- Cross-platform (Windows, macOS, Linux)
- Familiar for Node.js developers
- Perfect for Claude Desktop users

## Package Details

### npm Package
- **Name**: `@mariodef/sap-datasphere-mcp`
- **Version**: 1.0.9
- **License**: MIT
- **Size**: ~12 KB (tarball), ~28 KB (unpacked)
- **Files**: 5 (package.json, bin/, README.md, LICENSE, CHANGELOG)
- **Dependencies**: None (only Python as peer dependency)

### Python Package (Auto-installed)

- **Python**: 3.10+

---

## Troubleshooting

### "Package name already taken"

If `@mariodef/sap-datasphere-mcp` is taken, you can:
1. Use your npm username: `@your-username/sap-datasphere-mcp`
2. Update `package.json`: Change the `name` field
3. Republish with new name

### "Need auth to publish"

```bash
npm login
npm whoami  # Verify you're logged in
```

### Postinstall fails on user's machine

This is OK! The wrapper script will:
1. Detect Python package is missing
2. Attempt to install it automatically
3. Show clear error if Python not found

---

## Next Steps After Publishing

1. **Update README.md** with npm installation instructions
2. **Create release notes** mentioning npm availability
3. **Announce on GitHub** with release v1.0.9
4. **Test on different platforms** (Windows, macOS, Linux)
5. **Update documentation** with npm examples

---

## Future Updates

When releasing v1.0.10:

1. Update version in both:
   - `package.json`: `"version": "1.0.10"`
   - `pyproject.toml`: `version = "1.0.10"`

2. Update wrapper if needed:
   - `bin/sap-datasphere-mcp.js`

3. Commit and push:
   ```bash
   git add package.json bin/sap-datasphere-mcp.js
   git commit -m "Bump version to 1.0.10"
   git push
   ```

4. Publish to npm:
   ```bash
   npm publish
   ```

5. Publish to PyPI:
   ```bash
   python -m build
   python -m twine upload dist/*
   ```
